Abstract: 1280067 Stepping motor control POLYGRAPH LEIPZIG KOMBINAT FUR POLYGBAPHISOHE MASCHINEN UND AUSRUSTUNGEN VEB 5 June 1970 27311/70 Heading H2J [Also in Division B6] Stepping motors M, having respective windings a-b, c-d, connected to control outputs y 1 -y 1 , y 2 -y 2  perform complete revolutions in response to an input pulse X, Fig. 9. The two windings are energized at once and current in them is sequentially reversed for stepping by 90 degree intervals. In Fig. 9, line B is normally at a potential L, and A at zero potential, with outputs y 1 , y 2  energized. A pulse at X gives a potential at A through " AND " gate 30, and " OR " gate 31 which passes through " AND " gate 39 back to 31 to render the potential A stable until the potential at B changes. The potential at A also passes through amplifier 32 and interchanges the potentials at y 1 , y 1  with the help of " NOT " gate 33, and after a delay provided at 34 passes through amplifier 35 to similarly interchange the potentials at y 2 , y 2 . After a further delay at 37 the signal causes " NOT " gate 38 to change its state, so that the potential at B goes to zero, causing the potential at A to go to zero, and be held as before by the operation of gates 31, 39. The change in potential at A causes y 1  and y 1  to interchange, followed sequentially by y 2 , y 2  in the manner described above, and after a further delay the potential at B again rises and the circuit is sensitive to further pulses at X, the motors having made one revolution in four steps. The input of control network 29 may be connected to a monostable multivibrator (40) Fig. 10 (not shown) to give a pulse of definite duration, or to an adjustable astable multivibrator (42), Fig. 11, (not shown), for continuous operation, or the multivibrator (42) may be incorporated in a circuit having an " AND " gate (43), a " NOT " gate (45) and a counter (44) Fig. 12 (not shown) so that a determined number only of pulses passes to 29, the potential at (C) disappearng after the required pulse count is reached. Fig. 13 shows a switching network for a set of stepping motors in each one of a number of inking devices in a printing press, motors M1.1.1, 1.1.2-MX.1.1- X 1.2, being in locations 1-X in one inking device, and motors M1.1.1,1.1.2-M1.X.1-1.X.2 being in corresponding locations in successive inking devices. Switches DA1-DAX connect one side of the windings of all the motors in inking devices 1-X to the control 29, and switches SA1-SAX similarly connect corresponding motors in position 1-X in each inking device, so that motors in given locations in a selection of the inking devices can be energized. The motor windings may be coupled to a pulse counter 6, Fig. 15, (not shown), or an indicating disc (49), Figs. 16, 17 (not shown), may be fitted. Indicating motors may be fitted on a control panel. Applications of stepping motors to a printing press, see Division B6, are given, Figs. 1-8, 18 (not shown).

Title: Improvements relating to polishing machines
IPC: A47L11/164
Filed: 1931-10-03
Abstract: 381,327. Floor-polishing machines. VORWERK & CO., 23, M³hlenweg, Barmen, Germany. Oct. 3, 1931, No. 27525. Convention date, June 13. [Classes 19 and 138 (i).] An electrically-driven floor-polishing machine comprises a stationary annular brush or mop, within which is mounted one or more rotary brushes adapted during rotation to exert pressure on the floor surface independently of their weight, or the weight of the machine. In the construction shown in Fig. 1, the stock 18 of a rotary brush 17 is slidably mounted on the shaft 13 of an electric motor, and is provided with radial slots containing looselymounted pins 20, which pass outwardly against a conical cover 19, as the brush rotates, thereby increasing the pressure of the brush on the floor. In addition, a vacuum is formed in the space within the bristles whereby the brush pressure is increased further. The brush is surrounded by a detachable stationary brush 14 which may be replaced by a mop. In a modification shown in Fig. 4, the brush stock carries curved vanes 22, which are acted upon by the atmosphere, as the motor rotates, so that the brush is pressed downwardly. In a further modification, the pressure is obtained by means of pivoted bell-crank levers acting through centrifugal force upon the brush stock. The bristles of the brush may be arranged as shown in Fig. 12, or so bent they approximate to the form of propeller blades, or they may be of length decreasing from the outer ring towards the centre of the brush, the lower surface of the brush stock being stepped or sloped accordingly, so that the free ends of the brush are in a common plane. In the construction shown in Fig. 8, a number of pivotallymounted brush backs 30 radiate from the motor shaft and are provided with weights 31 which act through centrifugal force to press the brushes downwardly. The construction may be modified by the brush backs being shaped to transmit air pressure downwardly as the brushes rotate, the weights 31 being dispensed with.

IPC: D01H1/36
Filed: 1958-08-28
Abstract: 870,620. Builder-motion. T.M.M. (RESEARCH) Ltd. Aug. 28, 1959 [Aug. 28, 1958], No. 27666/58. Class 120(2) Relates to mechanism for reversing the direction of motion of a lifter-rail in a machine such as a flyer-frame of the type comprising a rocker 13 oscillating synchronously with the lifter, a second rocker 11 which can oscillate to reverse the direction of movement of the lifter, and is resiliently connected to rocker 13 so as to oscillate with it except when restrained by catches 15, 16 which hold rocker 11 stationary except when tripped and disengaged by means 22, 23 associated with rocker 13 when the lifter reaches each end of its traverse. In such mechanism, to ensure that the reverse gears engage properly when the machine stops, e.g. by the operation of a stop-motion, when the lifter is near either end of its traverse, auxiliary means are provided which respond to the stop-motion and to the lifter being at or approaching either end of its traverse. Rocker 11 is connected to a shaft carrying two opposite bevels one of which, as it rocks, is brought into engagement with a driving- pinion to drive the traverse one way or the other. Rocker 13 carries a shaft 14 connected to the rail lifter and has arms carrying adjustable spring-loaded plungers 22, 23. When the lifter reaches an end of its traverse, rocker 13 is moved to a position where one or other of the plungers bears on the corresponding catch to release the rocker 11 to be swung by one of two springs by which it is connected to rocker 13 to effect reversal of the traverse. When a catch is released it rides on the upper part of rocker 11 as is shown in the case of catch 16 and closes the appropriate one of two microswitches 28, 29. Immediately before the traverse is reversed there is a moment when both switches are closed. The switches are in circuit with a third switch which is closed when the stop-motion is brought into operation; when all three switches are closed a solenoid 18 carried by rocker 13 is energized so that an armature 19 descends against a spring 20 for a bracket 21 to force the plungers 22, 23 to descend and bear on the catches whereby reversal of the traverse is ensured.

IPC: G06F7/52
Filed: 1949-10-31
Abstract: 718,591. Digital electric calculating-apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Oct. 31, 1950 [Oct. 31, 1949], No. 27880/49. Class 106 (1) In an electronic circuit for' multiplying-digit binary numbers, comprising- a shifting multiplicand register and parallel adder each of 2 stages, corresponding stages being connected through gate circuits, the multiplier is fed in serial form to all the gate circuits so that for every " 1 " digit of the multiplier the multiplicand, shifted into an appropriate denominational position in the register, is allowed to pass to the adder. The circuit shown is adapted to be incorporated in the machine of Specification 705,479 and comprises a known shifting register and parallel adder having in each stage a trigger circuit TRC 1 ... 80, TCB 1.80 respectively, e.g. of the Eccles-Jordan type. The 40-digit multiplicand, applied in serial form to line 23, is initially entered into the register by the application of specially-timed digit-selecting p-pulses, e.g. see Fig. 3, c-e. to gates ING 1-40, and is shifted stage by stage by pulses, Fig. 3b, on line 10 which, for each trigger TRC in which a " 1 " it registered, reset the trigger and produce an output pulse sent through a delay circuit DLN 1-79 to set the next higher trigger. The contents of the register are passed to the adder via gates GA 1-80 which are opened by the " 1 " pulses of the multiplier signal, Fig. 3a, applied over line 13. In the adder, all "carries" are accomplished simultaneously by pulses, Fig. 3f, on line 12 which pass through gates GC 1-79, and possibly through inverters TNV and gates GD 2-79, to delay circuits DNW 1-79 and the triggers TCB 2-80. A gate GC is opened by a corresponding gate GB if " 1 " and " 0 " are registered on triggers TRC, TCB respectively, and a gate GD is open if " 1 " is registered on the corresponding trigger TCB. The sum registered in the adder, available in parallel form on leads OL 1-80, may be read out in serial form on line 30 by applying p-pulses to gates ONG 1-80, and the triggers TCB may be reset by a pulse on line 31. In a modification, the multiplicand in serial form may be entered in the shifting register by applying it to the first or last trigger circuit while sending a succession of reset pulses  : ÷ver a line 10. Specification 712,172 also is referred to.

Abstract: 225,238. Bellini, E. Nov. 24, 1923, [Convention date]. Directive signalling. - Relates to directional apparatus particularly applicable in cases where the two main loop aerials are of different dimensions as in aircraft installations. Instead of using electromagnetic or electrostatic coupling between the fixed and moving parts of the radiogonometer, .the signal voltages from the main coils are applied to a high resistance or potentiometer, the points of maximum or minimum reception being indicated by a balancing pointer sliding over the potentiometer. As shown in Fig. 1, the frame aerials are connected to terminals 2 arranged at intervals of 90‹ on a circular high-resistance wire or graphite 1, and the balance point is indicated by two insulated pointers 3 connected to an amplifier and forming a diametral arm rotated by a button O. In Fig. 5 the high resistance consists of a suitable electrolyte 2 contained in a vessel 1. The frame aerials are connected to four fixed plates or wires 3, and the amplifier to two moving plates or wires 5. The voltage curve for a complete rotation of the arm 3, Fig. 1, is triangular as shown in Fig. 2, instead of sinusoidal, when the transmitting station is in the plane of one of the receiving frames. When the direction of transmission is inclined at an angle of 45‹ the characteristic curve is trapezoidal as shown in Fig. 3, and for other inclinations the curve is more or less deformed.

Abstract: 279,646. Holbrook, R. E. Nov. 9, 1926. Turning. - In a screw-cutting lathe the acting face of the sta tionary thrust member of the lead screw is adapted to tilt in any direction transverse to the axis of the screw and thus prevent periodic errors in the pitch of the screw being cut due to inaccuracies in the thrust face. The lead screw 2 is reduced at 5 to provide a collar at the end, thrust in one direction being taken by a face 3 of the collar and in the other direction by a face 4. A thrust washer 9, preferably of chilled phosohor bronze, bears against the surface 3 and has a conical recess 12 to receive a spherically ended pin 10 adjustable, for taking up wear, in a casing 7 attached to the end bearing 6 of the lead screw. A second thrust washer 19, which is U-shaped or divided to pass over the end of the lead screw, bears against the face 4 and against an integral ring 16 having a spherical surface for engaging a conical recess 15 in the bearing 6. The bore of the ring 16 is large enough to pass over the end of the lead screw, and if the washer 19 is split, a spigot 22 is provided for retaining the two portions together. Rotation of the thrust washers is prevented by pins 13, 20 in the casing engaging axial slots in the grooves. The casing, which may be locked in position, is provided with peripheral notches for rotation by a hook spanner and may form an oil-tight cover for the bearing.
